Understanding Domain and Range in Math: Key Concepts and Practice Exercises - api

What is the Domain and Range of a Function?

The domain of a function is the set of all possible input values for which the function is defined. In other words, it is the set of all possible x-values that can be plugged into the function.

Domain and range are essential components of functions, which are mathematical relationships between variables. The domain of a function is the set of all possible input values, while the range is the set of all possible output values. Understanding domain and range helps students visualize and analyze functions, which is crucial for problem-solving and critical thinking.
